Compute the answer of the following problem
Problem- A body weighing 2 pounds will stretch a spring 4 inches. This same body is attached to such a spring with no accompanying dashpot. At t = 0, the body is pushed downward from equilibrium with a velocity of 8 inches per second.
Part 1- Find a mathematical model that represents the motion of the body and solve.
Part 2- Determine the resulting motion. After release does the mass every cross equilibrium?
I need assist to determine the resulting motion in body.
